Abstract
We have examined the influence of rotation on the potential energy and the transport coefficients of the collective motion (friction and mass coeffici ents). For axially symmetric deformation of nucleus Th-224 we found that at excitations corresponding to temperatures T greater than or equal to I MeV the shell correction to the liquid-drop energy practically does not depend on the angular rotation. The friction and mass coefficients obtained withi n the linear response theory for the same,nucleus at temperatures larger th an 2 MeV are rather stable with respect to rotation provided that the contr ibutions from spurious states arising due to the violation of rotation symm etry are removed. At smaller excitations both friction and mass parameters corresponding to the elongation mode are growing functions of rotational fr equency omega (rot). (C) 2001 Elsevier Science B.V.
